Dear all, It seems that maxima code blocks still does not work in windows as the following code did not work when I tried to run it: #+begin_src maxima a: 1+1; print(a); #+end_src This is an old issue already emailed to this emacs org-mode list in an email dating from june 2011. The conversation ended up with a final reflection which I copy next: >* Okay, it definitely is a Windows problem. If I run the following command* >* in a cygwin shell, everything works as expected:* > >* maxima --very-quiet -r* >* 'batchload("c:/Users/weiss/AppData/Local/Temp/babel-17716aLH/maxima-17716hCp")$'* >* nil* > >* However, it does not work in a Windows shell. But this is no longer an* >* org issue.* > >* Bernd* Trying to find the correct string that makes maxima execute the batch file in windows I found that this command does work: maxima --very-quiet -r "batchload(\"c:/Users/alvaro/AppData/Local/Temp/babel-7740OHt/maxima-7740OpY.max\")$" maxima --very-quiet -r "batchload(\"c:/Users/alvaro/AppData/Local/Temp/babel-7740OHt/maxima-7740OpY.max\")$" 2 I tried to make this string when maxima is executed in the shell and modifying ob-maxima.el found that this seems to work for windows 8, emacs 24.4 and org 8.2.7b: (let* ((cmdline (or (cdr (assoc :cmdline params)) "")) (in-file (org-babel-temp-file "maxima-" ".max")) (cmd (format "%s --very-quiet -r \"batchload(\\\"%s\\\")$\" %s" org-babel-maxima-command in-file cmdline))) The problem is that my lisp skills are not very good, to say the least, and sending a patch is one more problem so I write this email if this can help anybody to makemaxima code blocks work in windows. Thanks, Juan Alvaro
